, by the simple performance of' certain mechanicali'unctions. le obtain this object by a novel mechanical contrivance which 1s concealed withinthe familiar lorm ofa cornet, and as the quality as well as the color of the tone can be made to resemble that of a cornet very closely, a person using and manipulating it skiltully may create. the impression of a genuine performance upon it. rl`he power require to operate the device is produced by linger y. assure upon the button of a pin, located in the positionol' and resembling the customary cornet valves, whereby the impression of a trueexbibition is greatly strengthened. A bar contains a series o'l` reeds, which are tuned in proper chromatic order. Each reed is located in an orifice and actuated by wind passing through the` latter which causes a metallic tongue to vibrate whereby the sound is produced. The required wind is blown into the mouth piece of the instrument. A musicsheet is passed over the bar by the mechanism, which. sheet is provided with corresponding openings whereby the res ective orifice containing a tune is periodical y covered and uncovered. Then uncovered, wind passes through the orifice, actuates a metallic tongue and produces a sound. The tempo or speed at which the succession of sounds may be produced can beregulated mechanically at the will of the person handling the instrument. In our device this is accomplished by a .more or less rapid manipulation ot the above mentioned button, whereby the power operating the mechanism and controlling its speed can be increased or decreased.

It will be readily apparent that instead of the metallic tongues, other sound producing devices actuated by wind may be employed. It may also be mentioned in this connection that instead of a single melody, harmonies can be produced upon this instrument, which shows that the musical possibilities of it are not exhausted with the detailedspeciiication as hereinafter set forth. For the purpose of a description it is sullicient, however, to refer to one mode ol'" producing 'melodies only.

The device is fully illustrated in the accompanying drawings, in which- Figure l, is a complete elevation of the uncovered device. Fig. 2 is a plan view, showing the relative position of the various parts. Fig. 3 is a detail of the ratchet attachment wherebyI the power spring' is held under tension.

Like characters refer to like parts throughout the various views.

Referring to the drawings, ay represents the casing within which the device is mounted. This casing is divided vinto two partsy of which a is the bottom box and a? the cover. Both parts are hinged together and can be closed by spring clip a3, as shown in Fig. 1l..

The wind is conducted into the bar containing the reeds through wind pipe B; pipe b receives the sound from sound chamber b and conducts it to the sound transmitter fl.

c and c represent valve buttons, ol which only c is useful while the other two are ornamental and riveted to the casing simply vfor the purpose of completing the exterior appearance of the instrument.

The power contrivance which moves the lmusic sheet will be best understood from drawings Figs. 1 and 2 in'which a is the casving, e the useful and c the ornamental buttons. c is fastened to a pin 1 by which the power mechanism is actuated. Fig. 13. This pin 1 is pivoted at point p to arm 2 and at point p to arm 3. Arm 2 is attached to toothed segment 2 while arm 3 is a part of spring housing 3', wherein spring' 4 is aty tached with one end to axle 5 and with the other end to the housing 3 as shownin Fig. 8. Arm 2 and its segment 2 are rigidly mounted upon axle 6, while axle 5 carries i lished as in Fig. 13.

' S and S2.

segmental gear'wheel 5 :which is fastened to axle 5 in line with toothed segment 2 whereon its inner sidepawl 52 and pawl spring 53,

which'pawl connects 'with ratchet wheel 82 when all the partsare slipped upon axle 5 inl their proper lposition. All parts carried by axle 5 fi. c. spring housing 3, gear wheel 8 with itsv two ratchet wheels 8 and A82, and spur gear 5 are rotatably mounted upon the saine, so that each one may revolve freely in the direction of the force moving it. Both axles are journaled in frame f and -7",as-

shown in Figs. 1 and 2. f is riveted to the side frames f 2 in such a way that the proper. distance between f and f for the free movement -of the above mentioned axles is main'- tained. yA ratchet wheel 9 is fastened to axle 5- outwardly of frame plate AA pawl 9 and spring 92 acts in correspondence with it, as shownin detail Fig. 3. This attachment serves the purpose of holding spring 4 in spring barrel 3 under any desired tension, before finger pressure is exerted upon button'c for the purpose of pressing down pin 1.

The double ratchet movement, as shown in Fig. 13, provides uninterrupted -movement of the gear wheel 8 land thereby of the music-sheet, as Awill be seen later. The power v'movement operates as. fllows1-Pin 1 is pressed down by finger pressure, whereby spring housing 3 is rotated around axle 5 a' corresponding distance. As pawl 7 isfastened toy spring housing 3, it will be carried with it 3 in so doing it glides down upon the ratchet teethof ratchet wheel 8. DuringA this movement the tension of spring 4 is in-'-V creased, so that when the finger pressure is removed spring housing 3 will revolve upon axle 5 in the directionof the spring tension, whereby pawl 7 engages with-ratchet wheel C and turns gear wheel 8 in the direction of thearrow as indicated in F ig. 1. It is' vevident that during the mterval of ltlme required to increase the tension of spring 4,y

another movement is needed to rotate the gear wheel 8. This 1s accomplished by seg- Apinion 10 and worm gear 102.

ment 2 in connection with spur gear 5 and pawl 52, which latterengages with ratchet wheel 82 of gear wheel 8 and rotates it during the full downward stroke of pin 1. In other wordsgear wheel 8 is rotated during the down-stroke of pin 1 by segment 2, spur gear5 and pawl 52 and when theV finger pressure is removed from buttonc it is ro- 'tated in the same direction by the tension of yspring 4 in connection with pawl 7 and ratchet wheel S. Axle '10 is also journaled in frame plate f and f 1. Fastened upon it is of frame f, fly-wheel 11 is secured to axle 10 by a pin 11 which passes through its hub 112. This fly wheel serves the steadying the speed of mechanical movement. Pinion 10 is in gear connection with gearwheel 8 which drives it. Worm gear 102 is in gear connection with worm 12 of axle 12, which latter is journaled in lug f3 and in lever 23 at a right angle to axle 10. Pinion 122 is fastened to axle 12 outwardly of frame plate f 2 where it transmits the movement to gear wheel 14, which. is secured to.

shaft 15 of spool 15. Shaft 15 is journaled in frame plates and f2 and during the rotating movement of spool 15 the music sheet is gradually unwound from spool 16 'and wound around spool 15. Spool lis'se- .cured to shaft 16 andjournaled in bosses 17 and 1,7", which are fastened to frame plates f2. Pinion 162 is rigidly vmounted upon pin 18 outwardly of frame plate Pin 18 is Outwardly purpose of rotatably secured in boss 17 by shoulder 18 )100 on one side and pinion 162 on the other. The

music sheet is hooked u on hook 22 of spool 16 and is wound on sai spool before the latter is inserted into its place in the. device, and its connection with pinion 162 and pin 18 is made easily interchangeable by providingv axle 16with a pin 163 at the end adjacent to pinion 162. Pln 18is provided with a slot 182 which receives in 1,62. At the other end of spool 16, a pin 19 containing av bore, wherein axle 16 is journaled, passes through boss-17 which is forced against the spool by v'spring 19. When spool 16 is to be removed, it is onlynecessary-to force back pin 19 against spring 19 whereby pin 162will be disengaged from slot 18, where spool may Joe-r'emoved. s

Between the two spools, reed bar 20 is upon thel located and is provided with orifices 20 and with a metallic reed or tongue 202 for each orifice. the bar and is fastened by means of its loop 21 to hook 22, which is placed midways between the two end iianges of spool 1'5.

When the mechanical movement is set into actlo'n, the music-sheet 1s drawn by 1t over bar 20 and wound around spool 1 5. When The music-sheet 21 is passed over.

theend of the music-sheet 21 is reached and all of it is wound around spool 15, itis necessary to rewind it upon spool 16. This is done by reversing the mechanic al movement, see Fig. 4. It will be recalled that the power vis transmitted to axle 12 by means of worm -12 and worm gear 102.

Atl the end nearest to the worm this axle is journaled in' lug j, on the other end it rests in slot 13 andisjournaled in the end of lever 23, which lever is pivoted at point p2 in frame f2. This lever maintains proper gear-connection between pinion 122 and gear wheel 14. When musicsheet 21 is to 'be rewound 'u' on spool 16',y

lever'23/is pressed down an inion 122is swung u wardlv in slot 13 asslnU-into ear D u D D When a melody 1s to be produced, it is necessaryT to pass the music sheet sufficiently tight over bar 20.so as to avoid loss of wind between the surface of the bar and the musicsheet, as all the wind is required to ass through such slots 212 as may be use to uncover the desired ,orifice containing the wanted tune. A simple means whereby this result is effected is shown in Figs. 5 and 7. -The music-sheet 21, which is being unwound from spool 16 to spool 15'., passes over the curvature'jof reed-bar 20, whereby its slots 212 periodically uncover the orifices 20 to produce the desired tune. The sound chamber t is a par-t of cover a2; it is proyided with two flanges 25 to which is fastened a t celluloid plate 25', which latter is 4provided with slots 252 to correspond with the orifices 20 inthe reed bar.A A strip-of felt 26 is placed on both ends of the bar-see Fig. 2,- which allows the music-sheet 21 to pass through the small space between 'Celluloid plate 25 and the curvedreed-bar 20, Without binding it. When cover a,2 is closed, the sound chamber b with itscelluloid plate 215 presses the music-sheet gently against the 'surface of the bar, so that no wind is lost between the surface of the bar and the musicsheet.A During action the wind which is blown into the mouth piece passes into the reed bar 20, vibrates the metallic tongue 202 which produces the sound, and passes out through orifice 20. i

1t will be seen from therabove description that the device is of so compact a nature` that it may be placed in a comparatively small instrument as for instance a cornet. lts mechanical movements differ essentially from the'devices ordinarily employed, as the large spring barrel which is usually the source of power and which requires an intricate clockwork mechanism, is entirely omitted: The power is created by the use of finger pressure upon a valve button, which greatly simplifies the mechanical contrivance lightens the device materially and gives the performance upon the instrument the air of genuineness. Similar devices may be placed in similar instruments and operated in a like manner; in that way it is possible to assemblea complete band using various instruments all of which are provided with devices constructed in accordance with the spirit and within the scope of our invention.
